Removing the injector is fairly simple. There is a fuel supply line (steel line) to each injector. There is also a return line (smaller one). Both of these lines will have to be removed. On the return line be careful not to lose the little compression washers. Remove the two bolts that hold the injector in place. The injector should pull out. Be careful not to lose the copper washer that usually comes out with it. Inspect the end of it. There should be tiny holes in the end where the fuel sprays out. Unless you have a injector tester you will have to take them to a Diesel mechanic and have them tested. They will hook them up to a machine that can apply the PSI required to see if they are working properly. It shouldn't cost that much.
Make sure you use rubber fuel line
The year, make, model and which line info would help.
Faulty fuel pump. Faulty fuel pump relay. Faulty fuel pressure regulator. Clogged fuel filter, pickup, or line. No fuel in the fuel tank.
there is no fuel return line on any sienna. the pressure is regulated at the pump and any excess fuel is dumped into the tank directly.
No, Only the supply line has to be submerged in fuel.
No, there is no return line. Because of the low pressure of fuel systems on carberated vehicles, there is no need for a return line.
the fuel return line is on your fuel rail. it is part of the Pressure regulator assembly. Please view my Bio for access to my Saturn help site. in the fuel folder, go to Fuel pressure lines. the return line is highlited in green for you
No.
A fuel return line should flow freely back to the tank. There may be a check valve on the fuel return line that prevents backflow from the tank to the regulator.
Put simply. Yes it does. The fuel return line comes off the bottom of the fuel pressure regulator and heads back to the fuel tank.
no
The fuel supply line is usually larger in diameter than the fuel return line.

Both types have a vacuum line running to them: On the 3.8 engine it is on the fuel injector rail (Metal Fuel Line) near the return line. On the 3.4 motor the fuel return line is mounted to one side of the regulator and it is attached to the fuel rail on the other side.
The larger line is the pressure line, the smaller line is return.
